CVE-2026-67335
better-auth versions before 1.6.2 fail to validate the OAuth state parameter against the stored nonce when using cookie-backed state storage without PKCE. Attackers can forge the state parameter and supply an attacker-controlled authorization code to create authenticated sessions bound to the...
CVE-2026-67331
CVE-2026-67331 affects better-auth SCIM, versions 1.5.0 up to but not including 1.7.0-beta.4. The vulnerability arises because non-organization SCIM providers are not bound to their creator by default, enabling an authenticated user to manage other users’ providers. Attackers can regenerate SCIM ...
